Initializing a List c#

List<Student> liStudent = new List<Student>
        {
            new Student
            {
                Name="Mohan",ID=1
            },
            new Student
            {
            Name="Ravi",ID=2

            }
        };
public class Student
{
    public string Name { get; set; }
    public int ID { get; set; }

}

Is there other way to write this? I am a newbie. I want to make instance of student class first and assign properties in list.

It is going to work as you've written in Visual Studio 2008 and 2010. This way you use object initializer, there is no need to invoke a constructor. Read more on How to: Initialize Objects without Calling a Constructor (C# Programming Guide).

List<Student> liStudent = new List<Student>
        {
            new Student("Mohan",1),
            new Student("Ravi",2)
        };
public class Student
{
    public Student(string name,int id)
    {
        Name=name;
        ID=id;
    }
    public string Name { get; set; }
    public int ID { get; set; }

}

Since Student is a reference type, you can indeed add the instances to the list first, and set their parameters afterwards:

List<Student> lst = new List<Student> { new Student(), new Student() };
lst[0].Name = "Mohan";
lst[0].ID = 1;
lst[1].Name = "Ravi";
lst[1].ID = 2;
